Add automationtool binaries

[Ludea]

When using docker run - it adamrehn/ue4-build powershell RunUAT buildCookRun my uproject the build fail because it don't find UAT.exe.

I need to compile my project with ue4 source, not the installed engine (build in adamrehn/ue4-package image).

[adamrehn]

The executable for AutomationTool is built automatically the first time RunUAT.bat (or RunUAT.sh under Linux) is run. However, this script is not added to the system PATH environment variable, so you will need to provide the full path to the script in order to execute it.

The full path to the RunUAT script is as follows:

• In the Windows container images: C:\UnrealEngine\Engine\Build\BatchFiles\RunUAT.bat
• In the Linux container images: /home/ue4/UnrealEngine/Engine/Build/BatchFiles/RunUAT.sh

Alternatively, you can use the ue4 uat command from ue4cli to invoke UAT without needing to worry about the platform-specific script path. The ue4cli executable is added to the system PATH, so it can be invoked directly by name.

[Ludea]

If I use full path, ie C:\UnrealEngine\Engine\BatchFiles\RunUAT.bat I have an issue. Error : Visual Studio and/or AutomationTool.csproj wad not found, nor was Engine\Binaries\Dotnet\AutomationTool.exe. Can't run the automation tool. If I use ue4 uat, I have the same message. Any idea what is wrong?

[adamrehn]

Are you running those commands from an interactive prompt inside the container or directly from the docker run command? Could you please provide the full docker run commands used to launch the containers (plus any additional commands entered if you used an interactive prompt) so that I can attempt to reproduce the error?

[Ludea]

I run directly from docker run command. The full comand is : docker run -it powershell C:\UnrealEngine\Engine\BatchFiles\RunUAT.bat BuildCookRun -nocompile -nocompileeditor -installed -nop4 -project=myproject.uproject -cook -stage -archive -archivedirectory=myrpject -package -clientconfig=Shipping -ue4exe=UE4Editor-Cmd.exe -clean -pak -prereqs -distribution -targetplatform=Win64 -build -utf8output

I try docker run -it powershell ue4 uat BuildCookRun -nocompile -nocompileeditor -installed -nop4 -project=myproject.uproject -cook -stage -archive -archivedirectory=myrpject -package -clientconfig=Shipping -ue4exe=UE4Editor-Cmd.exe -clean -pak -prereqs -distribution -targetplatform=Win64 -build -utf8output , I have the same issue `

[adamrehn]

A couple of minor points:

• Those are not the full docker run commands, since they are missing required arguments such as the image name. I am assuming you are using the image adamrehn/ue4-build:4.20.2.
• The path you've specified for RunUAT.bat is missing the Build directory. The correct path is C:\UnrealEngine\Engine\Build\BatchFiles\RunUAT.bat.

However, with the image name added and the correct path used, I am indeed able to reproduce the error you have described when running both commands. The cause of the issue appears to be the inclusion of the -nocompile flag, which instructs RunUAT.bat to not compile the executable or scripts for AutomationTool. This flag is only appropriate when using an installed build of the Engine, as demonstrated by the fact that it works correctly with the adamrehn/ue4-package:4.20.2 image.

Solution: removing the -nocompile flag fixes the problem and both commands then run successfully.

[Ludea]

Yes, sorry, I did not copy all docker command (damm ctrl c / ctrl v !)

I remove the -no-compile flag. But I can't still build my project. Failed to find command C:\UnrealEngine\Engine\Build\BatchFiles\RunUAT.bat (see C:\UnrealEngine\Engine\Programs\AutomationTool\Saved\Logs\Log.txt for full exception trace)

My full command : docker run -it adamrehn/ue4-build:4.20.2 powershell ue4 uat C:\UnrealEngine\Engine\Build\BatchFiles\RunUAT.bat BuildCookRun -nocompileeditor -nop4 -project=Z:/myproject/myproject.uproject -cook -stage -archive -archivedirectory=Z:/myproject -package -clientconfig=Shipping -ue4exe=UE4Editor-Cmd.exe -clean -pak -prereqs -distribution -targetplatform=Win64 -build -utf8output

Maybe another flag issue ?

Update : Fix (delete RunUAT path)

[Ludea]

I don't know how share volume between windows server and windows container. (I know how do that on Linux). I try docker run -v fullue4projectpath:C:/-it adamrehn/ue4-build:4.20.2 powershell ls C:/ But I cannot bind by this way : invalid bind mount spec "Z:/ue4:C/:": invalid volume specification: 'Z:/ue4:C/:': invalid mount config for type "bind": destination path cannot bec:orc:`: c:.`

[adamrehn]

The error message already tells you exactly what the problem is: you cannot bind-mount a host path to the root of the C:\ drive, you need to specify a directory name. This is also not an issue specific to the UE4 containers but to all Windows Docker containers, and the ue4-docker issues list is not the appropriate place to ask questions about general Docker features such as bind-mounting.

I keep getting RunUAT.sh: not found too. here is my

@WSPluta: To make a code-block, use triple-backticks (```) rather than single-backticks.

As far as your actual issue goes, does /media/bm/Linux/Engine/Build/BatchFiles/RunUAT.sh exist? I'm not actually familiar with the official images from epicgames, so I don't know if /media/bm/Linux/Engine is where the installed Engine is normally found. I would expect from the Epic docs that this path should be /home/ue4/UnrealEngine/Engine/Build/BatchFiles/RunUAT.sh, the same as normal ue4-docker usage.

[WSPluta]

thanks. Yes it definitely exists and I can cd into it from my terminal

I have downloaded latest ue5 for linux, and installed it on my dedicated spare drive (called Linux) - so it is not located on the drive that I use to host my Ubuntu OS.

Ah, are you trying to use a UE5 install from outside the container? Your DockerFile's COPY isn't including the engine from your host, just the project.

If you're using a UE5 install from outside the container, then you're probably using the wrong container image, the point of the dev image is that it bundles a build of the engine. I think you maybe want to be using the Runtime container?

Anyway, this is a different issue from this ticket (which is about finding the RunUAT.sh inside the container), so I suggest you open a new ticket so it's visible to more people, although it's really general "DockerFile" help you need at this point.
